FISHERIES. — The migration of salmon in the Columbia River. Charles 

 Wilson Greene. Bulletin of the Bureau of Fisheries, 29 : 129-148. 

 Pis. 26-27. 1911. 

 On August 14, 1908, at the State fish hatchery at Chinook, Washing- 

 ton, there were liberated 25 chinook saimon, 16 silver salmon, and 18 

 steelheads which had been marked by means of an aluminum patent 

 button clamped through the tail fin. Seventeen fish out of this total 

 of 59 were retaken and reported, and upon their careers as indicated 

 by place and date of capture are based the following conclusions, -which, 

 however, because of the preliminary nature and limited extent of the 

 experiment, are presented as tentative: (1) Salmon may take from 30 to 

 40 days to pass through the brackish water within the limits of the fish- 

 ing waters at the mouth of the Columbia River. (2) That salmon 

 spend considerable time swimming back and forth in tide water during 

 the acclimatization to fresh water is indicated (a) by the fact that two 

 fishes were taken below the point at which they were marked, (b) by the 

 corrosion of the aluminum marking buttons by salt water, and (c) by 

 the long time spent by certain fishes in reaching the lower limits of fresh 

 water. (3) When wholly within fresh water, the silver salmon and the 

 steelhead make the migratory journey at an average speed of from 6 to 1\ 

 miles a day and probably more. (4) There is little evidence that the 

 process of marking or that partial obstruction of the course by fishing 

 gear does more than produce a temporary checking of the migratory 

 journey. E. M. Smith.
